The Logic Verdict

Check the Tap. Usually the water supply valve is turned off or the hose is kinked.

What It Means

The H20 code is literal: Water issue.

Common Causes

  1. Water supply valve under sink is closed.
  2. Inlet screen on the valve is clogged with sediment.
  3. Flood float is stuck in “up” position.

Step-by-Step Fix

  1. Check Valve: Ensure the knob under the sink is fully open.
  2. Check Float: Wiggle the plastic mushroom thing in the bottom of the tub. It should move up and down freely.
  3. Clean Screen: Disconnect hose from dishwasher and clean the mesh screen.
